Karthus Build Guide
Karthus is an unusual jungler: his damage stays a problem for the enemy team even once he has been killed, and ranked numbers on patch 16.13.1 put him at a 48.87% winrate with a niche 1.21% pickrate. Players who like his wave clear and poke can also take him to bot lane alongside a duo partner.
Dark Harvest rewards him for landing kills from long range, and pairing Blackfire Torch, Shadowflame, and Rabadon’s Deathcap turns his ultimate into a match-ending threat. Level his abilities in the order Q, E, then W. Complete itemization and matchup counters follow below.
